Hello, guys!

How many of your phones suffer from this problem? What's the first two digits of your S/N?
Mine is F17 and flickers...

Every unit I saw is suffereing from this problem, exactly the sane was with iP5S. Bellow 10% of all units I've seen are free of this "scan lines" issue.

Does the screen function normally other then showing a full image of the supplied screen? I think this goes back to people posting white screens (or checker board images) and then complaining about an issue which only occurs under the most abnormal conditions.

On gray or blue background I can see some fine vertical scanlines actually in normal usage...

Ah, I remember this problem from the 5/5s days. Kind of annoying that they didn't fix it. It's pretty easy to notice for some people (especially for me thanks to astigmatism (vertical lines show up nice and sharp compared to everything else)).

It was expected. 5S screens, now used for SE, had interlacing issue. Not sure how widespread, but many (including all 5S' I've exchanged, friends' 5S' and store demo units) had this issue. It feels like view the phone through a small net, especially on blue colors...

If you decide to return the phone, hopefully your next one is free of this issue!

My iPhone 5 screen flickers on that image, but I haven't seen the same effect elsewhere.

Not an issue for me.

Guys, I forgot to mention that your screens should be on full brightness while the test image is opened. Pls try it this way and share the result..

Also please keep in mind that not all people see those at all. It depends on eye construction. Do you also see diagonal lines when you tilt the phone to the right or left? Those can be seen under the LCD on the white layer, it's really hard to explain, but I could see them in every iPhone 5/5s, now on SE and some iPhone 6, on the 6Plus they're still there but much smaller almost not visible. Most of the ones I've asked don't see those either...

Of course I see them...
Had those on my 5S, very obvious, but without vertical interlacing. Now on my SE the diagonal lines are not so visible, but I see the vertical ones...

I think those are touch sensors. I hope they integrate them differently this year. They're actually pretty visible

Nope, these I can see clearly when the display is off. And they run up and down, left and right, not diagonally. It's different. And you can't see them when the display is on. What I'm talking about is diagonal lines on the backlight layer under the LCD, when you look at the phone when you tilt it to the left or right. This is not something consistent and varies from phone to phone but it's usually there.
And this is what I'm talking about. Not everyone can see those lines. But I do, I can see these in most other displays of other manufacturers so this is not strictly an Apple thing. Also the interlace/scan lines for example very visible in displays from the Sony Xperia Z3 Compact and other cheaper phones.
I'm really hoping that Apple will start using OLED displays, maybe not perfect but don't have any backlight issues (as there is no backlight layer) nor scan lines. So there it goes, my eyesight is way beyond the retina model, but as everything it will go worse while aging so I guess in a couple of years I will stop noticing those 'flaws'. BTW, my 14 year old daughter sees these also, so I'm not crazy or anything :)

I remember this on the 5, wasn't fun :(

the grey in the camera looks really runny, easier to see perhaps if you hold the phone in landscape and look at it, it looks horizontal interlacing then (obviously)

The phone screen is progressive scan, no interlacing involved. What you may be seeing is moire effect ... something that occurs when image elements are slightly larger or smaller than the pixels on the screen that is displaying the image. It is a very old phenomenon and not an indication of a problem with the screen, and it diminishes as screen ppi gets smaller.

I am wondering if I can ask in Apple Store to get a new unit with first digits of the S/N "C3". I am still in the 14-days returning frame..

Maybe so, but when you see the screen flicker and vertical lines especially on gray and blue then this is not moire effect. And either you see it or not, it also doesn't always appear, usually when there is movement on the screen. It's 100% screen fault.

I recently purchased two SEs, one 64GB model just as they were purging stock in preparation for the 128GB release, then I purchased one of the 128GB because they were being heavily discounted. Just my luck that the 128GB unit is the one with the inferior screen.

The 128GB unit's screen is inferior in multiple ways.

Firstly, it has the issue described in this thread. There is flicker with the supplied slide at higher brightness level, a weird flicker that messes with your brain because it's right on the edge of perception when looking square at the screen, but becomes more noticeable when you're moving your eyes. This is the kind of flicker that I can imagine some people being more sensitive to than others, and maybe some people can't see it even if their phone is doing it. I haven't seen any pseudo scan lines or flicker in normal images (yet), so I would probably not have been too worried about this one issue in isolation. The 64GB unit has zero flicker on that slide, regardless of brightness.

The 128GB unit's screen is also noticeably warmer, and it's blacks aren't as deep. The backlight brightness is the same, but the 64GB unit has less "glow". The distinctly different black screen characteristics make me suspect that, in addition to the A9 lottery, the iPhone SE might also be subject to a LCD panel lottery.

For the record, the serial numbers on both units start with DX3.

Another old thread, rekindled.

I guess Apple should stop selling the SE. They are not going to redo it with an OLED screen so it is the choice of the user to buy or not. Most would never notice this, so for a few it will just be torture.
